SPECIFICATION forming part of Letters Patent No. 303,106, dated August5, 1884.

Application filed March 7, 1884.

Zo all whom may cole-cern,.-

Be it known that I, ARNOLD W. ZIMMERMAN, a citizen of the United States,residing at Chicago, in the county Yof Cook and State of Illinois, haveinvented certain new and useful Improvements in Gar-Doors, which arefully setv forth in the following specification, reference being had tothe accompanying drawings, forming a part hereof, and in which- Figure 1is a side elevation of a car with the door in placcand locked. Fig. 2shows the same parts as'Fig. 1, with only the lower door closed and theupper Vone opened. Fig. Sshows an end elevation of the door on a plane,Y Y, which cuts the ear only on the joint of the door, and shows theleek and door in place, as shown in Fig. 1. Fig. 4.- is acrossseetion ofthe car on the plane Y Y, which cuts the car only and shows the entiredoor open and all its parts in their relative position in end elevation.Fig. 5 shows a crossseetion of the ear on the plane Y Y, with the doorand its parts in end elevation, of which the lower part is closed andthe upper one open, as shown in Fig". 2. Fig. 6 is a plan view of one ofthe studs c'.

Like let-ters of reference indicate like parts.

The object of my invention is to improve the construction patented to meJuly 10, 1883, and numbered 281,170; and it consists in the better andsimpler fastening devices for the lower door, and mechanism to hold itinits place, so that it cannotbe removed when the upper part of the dooris open, and in an at-` tachment whereby the lower part of the door maybe prevented from swinging outward, or may be made to do so, all ashereinafter more fully specified.

In the drawings, c represents the lower and b the upper parts of mydoor, (shown attached to my improved car-door lock, which isrthe subjectof another application pending, iiled of even date` with this, No.123,320.)

I make no claims in this application to the car-door loclc mechanismherein shown, as it forms the subject of claims in said otherapplication, and it and said locl; are both improvements on Patents Nos.281,170 and 282,589, granted July 10 and August 7, respectively.

af" is the frame of the door, of which the sides are shown slightlybeveled.

a3 are inside stops overlapping the joints of (No model.)

the door and frame, and l are blocks att-ached to the sides of thedoor-frame, cut on such an upward bevel as to allow the slot or notch Z,cut in the vertical edges of the door a to pass over it freely.

b is a spur upon the upper door projecting inward beyond the inside ofthe door. Said spur rests upon the lower door and holds it from beinglifted out when the upper door is open. The lower edge of the door a, isheld in its place bythe eyebolt q, through which passes the pin p, whichforms a part of the wing p of a hinge, of which the straps r form theother part, said parts p being bolted to `the lower and r to the upperpart of the door a b. The part a may also be held in its place by acleat fastened to the side of the car, and

4projecting up so as to cover the lower end of 7o the door a, orupward-pointing hooks or other like devices maybe used. The upper partof the door a is held in place by the beveled 0r upwardlyv and outwardlyinclined and parallel-sided blocks Z', vwhich lit into correspondingnotches, Z, out out of the edges of said door. Said .blocks and notches,it will be observed, prevent the door from moving in 'either an inwardor outward direction, .unless the door is lifted upward at the sametime, and then it can move outward only.

The upper edge of the lower door is beveled inward and downward from theoutside. upon which the lower edge of the upper door ts. Thisconstruction prevents the lower part of thevupper door from swingingoutward, and the stops ai* prevent it from going inward, as

valso do the straps r, which overlap the lower door, and also work tothe best advantage with my improved door-look. To the center of thelower door is bolted a hook, it, of which the horizontal part h passesbeyond the thickness of the edge Il, forming a part of the ear, farenough to permit the door to swing out far enough so that when the pointIl? strikes against 'the inside of Il?, as shown in Fig. 4, the door mayslide freely past the side of the car. Said hook It prevents the lowerend of the door from swinging out when released from the stops q, andthus discharging too large a part of the load from the car withoutcontrol of such materials as would run out. The straps 'r overlap thedoor a. until they meet the straps p, where they are formed into themale part Za and female part 7a2 of a hinge, which are united by thepintles a n2. Said pintles form the parts of a rod, a, of which one partis bent into the form of a hook, of which Vthe part forming the rod apasses through a lug, k3, which holds the point a2 of said hook, so thatit may slide in and out of its place in the hinge. of the hinge k2. Onthe rod n is also a knob, 1f, fixed to the rod a, so placed that whenthe pintles' a2 a are withdrawn from the hinge it will strike againstthe side of the strap p and'prevent the pin n from coming out of itsplace. Said knob at also serves as a handle by which to push the rodback and forth. Vhen the parts r and p are separated the part of the roda? slides into a staple, a3, and thus prevents the door from beinglifted out of its place. The eyes z are placed near the upper corners ofthe door b, and through them passes a rodcZ, which forms the pint-le ofa hinge, g, in the lower end of the bell-crank or hook g2. rIhe upperend of said hook forms a hinge-joint, gf, with the hook g, which slidesupon the bar c. Said bar c is fastened under the eaves of the car byscrews cr bolts, countersunk, or flush with its outer face, and which issecured to posts c', through which pass screws securing said parts tothe car. The flat bar cV is preferable to a round rod, as it can bestayed at any desired points by posts c', which permit the hook g toslide freely, which cannot be done by a round rod, as it can only besupported at its ends, and is therefore weaker even with much heaviermaterial. The parts gf* form a hinge-joint with the parts f g2 and thelower end of f is provided with a thread, into which screws the thread fofthe rodf, and the lower end of said rod is formed into an eye, whichworks upon the crank-pin jf* in the hook j. By this construction the rodf is adjusted to its proper length. The hook j is fixed to the shaft e,and turns with it in the boxes 7c, which may form a part of the strap r,or be part of a separate piece,

, 0, which is riveted to the straps i', and has upon its lower end theparts 7c k2.

Upon the center of the rod e is fixed a lever, t, which is hinged nearthe shaft e, so that it may move freely in a plane passing through itand the axis of the shaft c. The strap r may be united by a strap, r',which covers the joint between the two doors, or the strap r may be aseparate piece attached to the upper door to prevent water from enteringat the joint. To the door a is attached a hook, t', under which thelever t passes when the doors are closed, and where it may be secured byalock, or otherwise fastened. attached one or more step-plates, m, uponwhich the lower section of the door rests when open, and which preventits being lowered out of its place, but keeps it ready to be shoved intoits place to close the car. The hook j works into an annular socket, j2,upon a pin, j, which together form one piece, which is set The end, n,rests in the inside part To the side of the car are into the door-frame;but the hook j may really be dispensed with and only the pin j used,this part thus forming merely a crank from which the hooks y2 areoperated, and then the door is held in its place only by the dovetailfastenings' Z Z at its upper end.

To open the door, bring the lever t out from under the hook t', and downto the position shown in Fig. 2, pull the lower end of the door outward,so that the parts h2 h3 come into contact, then slide it back from theopening.

To spring the entire door outward from the cars, as shown in the dottedoutlines of Fig.

.4, bring the lever t back toward its original position. This motionwill pass h2 below h3.

To open the upper door only, first shove the rod n into a. This willseparate the hinges. 'Ihen operate the lever t, as. before, and shovethe door b back. The part f projects into the wall of the car when thedoor is closed, as shown in Fig. 3, and for that purpose a place is dugout for it.

What I claim is- 1. The door a, provided with fastening mechanism at itslower end, and notches Z near its upper end, and blocks Z', formed withedges cut on a bevel, substantially as specified.

2. In combination with the door a, provided with fastening mechanism forits lower end, and notches Z, and blocks Z near its upper end, the doorb, and mechanism to operate said doors, substantially as specied.

3. In combination with the door a, provided with fastening devices forits lower and upper end and hook L, the guide h, and meehanism forlifting and sliding the door, substantially as specified.

4. The door a, provided with fastening devices for its lower and upperend, in combination with the door b, provided with spur b', andmechanism whereby one or both of said doors may be lifted and slide fromand to their places, substantially as specified.

5. In combination with the lifting, sliding, and separable doors a b,the separable joints uniting both doors by pins n a, substantially asspecied.

6. A car-door fastener consisting of mechA anism to hold the lower endin its place, and inclined blocks Z, attached to the sides of the frame,and fitting into corresponding notches eut in the sides ofthe door, nearits upper end, and rod a and staple a, substantially as specified.

7. In a sliding car-door, mechanism to hold its lower end from pushingout, and upward and outward inclined blocks Z', attached to the frame ofthe door, and corresponding notches in the sides of the door, near itstop, to lit over said blocks Z', in combination with mechanism to liftsaid door upward and outward, substantially as specified.
